,"530 1A scupperwof this kind is installedY flush with the lower edge of `a 4roof oriloor, it extends through thewall thereof and has a discharge at the opposite side with one ormore gates therein and usually atthe discharge end, which are t 3,5 `immediately opened by a rush of water from the inside toprovide an escape for water or other f liquid in the caseof a fire, the accidental breakkind which may occur in a building,` and will pre- .vent the accumulation of a damaging amountof` uq'uid.

Referring now more particularly to the draw- `3 ing, a metal casing consisting of a substantiallyV i straight portion `I and a connected outwardly 45 flared portion I I are installed in an outer or partition wall I2 of a building with the inner edge 'of the casing substantially at the top level of a roof or floor I3,`the lowerside or edge I4 of the casing being inclined downwardly. from the iioor 50 `so that any water or otherliquid on top of the oor will flow through the casing to the discharge end thereof. p The outwardly-flaring portion has an upwar offset I5 and at the sides of this flaring portion 5 are installed gates I6 each mounted at the inautomatically closed and remain iniclosedposi-` ing of a pipe, or any other vemergency of` this ner edge upon auf-inclined hinge pin I'I` so that I each gate tends to swing forwardly to close the frontlofl'the casing, and. when swung rearwardly @it engagesthe wall of the outwardly flaring por- 'tinl I Ntoiofferno obstructionto liquid passing 5 .thereingl l i Af'front `or gratinglplate ,23 is coinmonlyprovided to lit over the inlet end `of the scupper and has a marginal rim for attachment tothe end of the casing and a number of spacedvertical bars V` 2Ito` prevent any large obstruction from being inserted in the inlet to :obstruct it in case `of a ilre.l ,.'I'his `front plate has rearward hinge pro- Hje'ctions 22 `and 23 in which the gates I5 are "mounted uponthe `hinge pins Il and the pro- '15- jectionsare disposed with respect to each other as clearly shown so that the hinge pins il are v inclined inwardly and forwardly atv the, top with respectto the sides `of the plate 2i) `so that the natural tendency of `the gate I6 pivoted at the 20 sides of the plate is to close inwardly and for- ,.wardly and to remain in this closed condition, l, easily balanced, sov thata very slightfrush `of l `water or other liquid will tend to openthe gate and to maintain it in open position. For con- ,25 Venience invassembling and attaching lthe casingf and assembling `the `parts therein, Athe top `is separately removable and a fastening bolt 24 extends from the bottom through the top and has a nut 25 for securing the top in place. At the 30 front of the top are projections 26 near the sides thereof which are seated in corresponding notches L 21` at the upper edges of the front plate 2l), and with a downwardly extending hook 28for engaging the `upper edge `of the front plate so that 35 in securing itin place the upper edge of the front plate is engaged below the hooks 28 and vfastening `screws 29 are inserted through the plate into a boss 30 at the lower edge of the front of the scupper. For additional protection the top 40 plate or the front upper edge ofthe front plate 20 may be `provided with a forwardly projecting `package guard 3l which prevents a package of any kind frombeing placed too close to the inlet of the scupper. 45

At the rear or discharge end of the scupper the casing as shown more clearly in Fig. 2 has an inclined edge which normally seats a gate 36 hinged at its upper end on a hinge pin 3'I in an overhanging extension 38 of the top plate. 50

A rush of water easily opens this gate 36 whichV allows'it to discharge freely from the end of the casing 4and usually at a distance from theA edge of the wall, and as soon as the water flow ceases the gate will be vclosed by gravity. l

water or other liquid on the roof or any oor of a building which prevents damage due to the presence of an unexpected amount of liquid in case of a fire or the breakage of a pipe or tank containing liquid. When not in use the gates' are automatically closed to form a dead air space between the inlet and discharge ends of the scupper and closing the wall against the ow of air or liquid in a reverse direction.

I claim:

l. A building scupper comprising a casing to extend through a wall with its lower edge at floor or roof level at the inside thereof, and a swinging door mounted upon a substantially upright pivot at one side of the casing and inclined so that the door is closable by gravity at the inside of the wall.

2. A building scupper comprising a casing to extend downwardly at a angle through the wall from a floor level, a grating mounted at the inner end of the casing and including pvot bearings substantially vertical but inclined inwardly at the top from the side of the opening, and a swinging door mounted on a pivot in the bearingsand closable toward the center by gravity at the inside of the grating.

3. Ina wall scupper, a casing having a grating at the inner end, and a pair of gates mounted at the sides of the casing upon substantially upright axes inclined inwardly at the top so that the gates will close inwardly by gravity against the inside of the grating.

4. In a wall scupper, a casing to extend downwardly through a wall having a gate at the inlet and means for mounting the gate on a substantially vertical axis extending inwardly and forwardly at the top of one side of the inlet opening so that the gate will tend to close the inlet opening by gravity.

5. In a scupper of the class described, a casing to extend through a wall having an overhanging projection at the top of the inlet end, a grating to t over the inlet end of the casing having a notch at the top to engage under the said projection, and fastening means at the bottom of the grating tol attach it to the lower edge of the casing.

6. In a wall scupper, a casing to extend through a wall and a grating for the inner end of the casing, a gravity closing gate mounted at the side of the casing and closable against the inside of the grating, and a package guard comprising a forward wavy extension of the grating at the top of the casing to space an obstruction therefrom.

7. In a wall scupper, a casing to extend through a wall having an inclined bottom and a aring inlet with a substantially flat top, a pair of gravity closing gates each mounted at the side of the opening and meeting at the center, and means lforming a substantially vertical axis inclined inwardly and forwardly at the top at each side of the opening so that the upper edge of each gate is substantially parallel with the top of the casing in open position, and inclines downwardly therefrom toward the center of the opening in its closed position.

8. In a wall scupper, a casing having its bottom inclined downwardly from the inlet to the outlet to project beyond the wall at the outlet end, a removable top for the casing having an overhanging projection at each end, a gate mounted in the overhanging projection at the discharge end to swing by gravity about a horizontal pivot, a grating engaging the overhanging projection at the top at vthe front end and secured to the casing at the bottom, and a pair of gravity closing gates mounted at the inside of the grating upon axes which incline forwardly and together at the top Vso that the gates tend to close the inlet by swinging downwardly against the inside of the grating.
